Enzymatic synthesis and application of fatty acid ascorbyl esters / Enzimska sinteza i primena askorbil-estara masnih kiselina
(Association of Chemical Engineers of Serbia, 2013)
Fatty acid ascorbyl esters are liposoluble substances that possess good antioxidative properties. These compounds could be synthesized by using various acyl donors for acylation of vitamin C in reaction catalyzed by chemical ...
Polymer bonded magnetic composites based on Nd-Fe-B / Polimerni magnetni kompoziti na bazi Nd-Fe-B
(Inženjersko društvo za koroziju, Beograd, 2013)
Various types and contents of magnetic powder and polymer matrix induce different mechanical, magnetic, electrical and optical properties of final composite material. The strong influence of relatively small amounts of ...
Spatial variations in the distribution of trace ionic impurities in the water-steam cycle in a thermal power plant based on a multivariate statistical approach
(Sciendo, Warsaw, 2013)
In this study, a multivariate statistical approach was used to identify the key variables responsible for process water quality in a power plant. The ion species that could cause corrosion in one of the major thermal power ...
Evaluation of antioxidative effects of twelve 3-substituted-5,5-diphenylhydantoins on human colon cancer cell line HCT-116
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2013)
Antioxidant effects of twelve 3-substituted-5,5-diphenylhydantoins in concentrations of 0.01, 0.1, 1, 10, and 100 mu M on human colon cancer cell line HCT-116 were determined 24 h after treatment. The concentrations of ...
The influence of substituted aromatic aldehydes on the electrodeposition of Zn-Mn alloy / Uloga supstituisanih aromatičnih aldehida u elektrohemijskom taloženju Zn-Mn legura
(Serbian Chemical Society, Belgrade, 2013)
Additives are necessary in the electrodeposition of Zn-Mn alloys at high current densities, in order to reduce the hydrogen evolution reaction and prevent dendrite formation. The influences of two aromatic aldehydes, ...
The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...
The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides / Uticaj rastvarača i strukture na elektronske absorpcione spektre izomernih piridin-karboksilnih kiselina N-oksida
(Association of the Chemical Engineers of Serbia, 2013)
The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen ...
Dissipation of pirimiphos-methyl during wheat fermentation by Lactobacillus plantarum
(Wiley, Hoboken, 2013)
In this study, the dissipation of pirimiphos-methyl during wheat fermentation by Lactobacillus plantarum was investigated. Sample preparation for GC/MS detection of pirimiphos-methyl residues from fermented wheat substrate ...
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Elsevier Science Sa, Lausanne, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to different environments (3% NaCl, atmosphere, and the Sahara sand) has been investigated. This system was also tested for ...
Impermeable layers in landfill design / Prilog projektovanju vodonepropusnih slojeva deponija
(Association of Chemical Engineers of Serbia, 2013)
Landfills are complex systems that could potentially contaminate the environment. This needs to be prevented by providing impermeability during the landfill design. In this aim, the related regulations should be followed ...
